Which of the following is true about CO_2CO
2
?
A
It does not have much effect on the climate.
B
It is a greenhouse gas.
C
Very little CO_2CO
2
is being emitted now.
D
If we cut CO_2CO
2
emissions by half, the temperature will stop rising.
Answer:
B.
Explanation:
It has a huge impact on the environment
It is being emitted in large amounts
And if we cut our carbon emissions in half it would delay the risk of raising the global temperature of 1.5 degrees Celsius but half of it would still pumped into the atmosphere along with the carbon dioxide already in the atmosphere.
But it is a greenhouse gas because it helps trap the heat remaining in Earth's atmosphere which is why the Earth is warming.
CO2 is a greenhouse gas.
what are greenhouse gases?
Greenhouse gases are gases in the atmosphere that affect the energy balance of the planet. The greenhouse effect is caused by them. Carbon dioxide (CO2), methane, and nitrous oxide, the most well-known greenhouse gases, can all be present in low concentrations in the environment.
The greenhouse gases in the atmosphere trap heat and warm the earth.
Carbon dioxide, methane, nitrous oxide, and water vapor (all of which exist naturally) are the principal greenhouse gases, as are fluorinated gases (which are synthetic).
Carbon dioxide (CO2) is released into the atmosphere as a result of the combustion of fossil fuels (coal, natural gas, and oil), solid waste, trees, and other biological materials, as well as chemical processes (e.g., manufacture of cement). As part of the biological carbon cycle, carbon dioxide is absorbed by plants and released from the atmosphere.
hence, CO2 is a greenhouse gas.

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in
compost bins, forming a dirt-like substance that's rich in nutrients. The next season, farmers use this
substance as a natural fertilizer for their crops.
A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer
formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in
unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to
grow faster and taller than his artificial fertilizer. Explain independent and dependent variables
Answer:
Please find the explanation of independent and dependent variables below using the experiment in this question.
Explanation:
Independent variable is the variable that the experimenter changes or manipulates in an experiment while the dependent variable is the variable being measured in the experiment.
According to this question, a biology student who has grown tomato plants for several years wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer, which he used previously.
In this case, the "natural compost" is the independent variable while the dependent variable is how tall and fast the tomato plant will grow. Hence, the tallness or fastness is the dependent variable.

Answer:
1) Create a hypothisis 2) Create experiment 3) collect data 4) write conclusion
The four steps that a scientist uses to solve a problem are creating hypothesis, experiment, data sorting and writing conclusion.
What are hypothesis?A hypothesis is an elaboration posited for a characteristic. The scientific technique requires that a hypothesis be testable in order for it to be considered a scientific hypothesis.
Scientists typically base scientific hypotheses on previous findings that cannot be adequately explained by existing scientific theories.
Any process that co-ordinate system data into some defined order to make it simpler to understand, analyze, or visualize is referred to as data sorting.
The conclusion is the final section of an academic essay. The conclusion should restate your response to the question and briefly summarize key points. It does not contain any new points or information.
A scientist solves a problem by developing a hypothesis, conducting an experiment, sorting data, and writing a conclusion.
Thus, by using these steps, scientist can come to an end for the problem.

What is the major difference during cytokinesis in eukaryotes with or without a cell wall?
Answer:
Cytokinesis in eukaryotic animal cells do not have a cell wall, it occurs through a strangulation process carried out from the plasma membrane, this process is called segmentation. Plant cells are characterized by cytokinesis based on septate, since the cell wall does not allow strangulation.
Explanation:
Cytokinesis means: cell division, it is a cellular process parallel to mitosis whose purpose is the division of the stem cell's cytoplasm between daughter cells. In animal cells, cytokinesis occurs by cleavage. At the end of anaphase and during telophase, the central part of the cell narrows, forming the segmentation groove, which deepens (strangulation). Plant cells, as they lack centrosomes, will form the achromatic spindle from two polar caps. In this case, cytokinesis does not occur by strangulation, but a cell wall is formed between the two daughter cells. This septum, called a fragmoplast, is formed from vesicles from the Golgi apparatus.
The major difference during cytokinesis in eukaryotes with or without a cell
wall is in the formation of cell plate in cells with cell wall while in animal
cells cytokinesis occurs through the formation of a cleavage furrow.
Cytokinesis is the process of cell division in which the cytoplasm divides
into two. Plants have cell walls while animals lack cell walls.
Animal and plant cells form cleavage furrow and cell plate respectively
which aids division into two equal parts.

Answer:
c. polyarthritis.
Explanation:
Rheumatic fever is an inflammatory disease that may affect different parts of the body including joints, heart, brain, and skin. It is a rare disease observed after a bacterial throat infection caused by Streptococcus (group A). The most common signs of this disease include swollen and/or tender joints (i.e., polyarthritis), especially in wrists, knees, elbows or ankles, fever, fatigue, pain in the chest, breathlessness, palpitations, etc. Rheumatic fever needs to be treated by antibiotics to eliminate group A Streptococcus infections.
Evaluate the evolutionary benefits of regulating an internal variable, such as body temperature, versus the cost.
Answer:
The benefits of being able to regulate the internal body temperature are many and it is considered a beneficial evolutionary character, since in this way the living organism is better maintained in relation to the environment, and it achieves better balance.
Reptiles cannot control their internal temperature, it depends on the external one, that is why to warm their body they need to be in the sun, and to cool down in the shade or in temperate places.
This is a little evolutionary characteristic since the environment is very changeable and the right or ideal temperature for the organism could not be controlled.
Explanation:
Faced with climatic catastrophes or extreme situations, living organisms cannot depend on the great climatic variants, in very cold situations one enters hypothermia and in very hot conditions the proteins are systematically denatured, entering a thermal shock.

In organisms other than plants, when and where is the most ATP produced?
in cytoplasm, during photosynthesis
in nuclei, during cellular respiration
in chloroplasts, during photosynthesis
in mitochondria, during cellular respiration
Answer:
D. In mitochondria, during cellular respiration.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
All living organisms such as plants and animals require energy to function properly (life activities). Thus, the organelle where energy from nutrients is released is generally referred to as mitochondria. Animals retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.
Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
In organisms other than plants, the most ATP is produced in mitochondria, during cellular respiration.
